The Mariana Islands, Palau, portions of the Great Barrier Reef, the main Hawaiian Islands, and the Florida Keys were surveyed. Flight line benthic cover measurements were collected by the Portable Remote Imaging Spectrometer (PRISM) instrument aboard an aircraft as part of NASA's COral Reef Airborne Laboratory (CORAL) mission. The dataset is version 1.0 and was last updated in May 2017.
Use Cases
- Mapping coral reef benthic composition based on spectral reflectance data.
- Analyzing regional differences in reef health across the surveyed geographies.
- Training models to classify benthic cover types from airborne spectrometer data.
- Providing baseline data for coral reef conservation and monitoring efforts.
Strengths
- Data originates from a NASA Earth Venture Suborbital-2 mission, suggesting a standardized collection protocol.
- Surveys cover multiple major reef systems across the Pacific and Atlantic, providing a broad geographic picture.
- Uses the PRISM airborne spectrometer, which is designed for coastal ocean and land observations.
Limitations
- Last updated 2017-05-28 23:59:59; freshness should be verified.
- Column-level documentation is absent; field semantics must be inferred after download.
- Row count is unknown, which may limit suitability assessment.
